The catbodic voltammetric charaatoristics of copper with linearly changing tension at the glassy carbon electrode in NH3-NH4Cl were studied in detail.The electrode reaction,peak tension,reversibility,peak current and temperature coeflioient were investigated.Experimental results showed that the reduotion of cuprammine complex cation was proceeded stepwisely at the glassy carbon electrode.Cu(NH3)2+4 was first reduced reversibly to Cu(NH3)2+,then to Cu irreversibly.
